Ä To serve as levers, working with attached muscles to produce movement. Ä To serve as a storehouse for calcium salts, which may be resorbed into the blood if there is not enough calcium in the diet. Ä To produce blood cells (in the red marrow).
3) Describe the structure of a long bone. This is the type of bone that makes almost the entire skeleton of the arms and legs. The long narrow shaft of this type of bone is called the diaphysis. At the center of the diaphysis is a medullary cavity, which contains bone marrow. The long bone also has two irregular ends. 1. a proximal. 2. a distal epiphysis.
4) Differentiate between compact bone and spongy bone with respect to structure and function. Compact bone is hard and dense. This makes up the main shaft of a long bone and the outer layer of other bones. Spongy bone is made of meshwork of small, bony plates filled with red marrow. Spongy bone is found at the epiphyses of the long bones and at the center of other bones.
5) Differentiate between red and yellow marrow with respect to function and location. Redmarrow is found at the ends of the long bones and at the center of other bones. Red bone marrow manufactures blood cells. Yellowmarrow is found chiefly in the central cavities of the long bones. Yellow bone marrow is composed largely of fat.
6) Name the 3 different types of cells in bone and describe the function of each. 1. Osteoblasts: Bone-forming cell. 2. Osteocytes: Mature bone cell; maintains bone but does not produce new bone tissue. 3. Osteoclasts: Cell that breaks down bone.
7) Explain how long a bone grows. During the second and third months of embryonic life, the conversion of cartilage to bone occurs. This process is called ossification. ¿¿ Bone-building called (osteoblasts) become active. First, they begin to manufacture the matrix. Once this intercellular material has hardened, the cells remain enclosed within the lacunae in the matrix.
8) Explain the purpose of the infant fontanels. The skulls of the infant had areas in which the bone formation is incomplete, leaving so-called soft spots. These flexible regions allow the skull to compress and change shape during the birth process. They allow rapid growth of the brain during infancy.

The Muscular SystemMs. Collins PNWHBOCES
1) Define Key Terms on page 110. JAcetylcholine: Neurotransmitter; released at synapses within the nervous system and at the neuromuscular junction. JActin: One of the two contractile proteins in muscle cells, the other being myosin. JAntagonist: Muscle that has an action opposite that of a given movement; substance that opposes the action of another substance. JFascicle: Small bundle, as of muscle cells or nerve cell fibers. JGlycogen: Compound built from glucose molecules that is stored for energy in liver and muscles. JInsertion: Muscle attachment connected to a movable joint. JLactic Acid: Organic acid that accumulates in muscle cells functioning without oxygen. JMotor Unit: Group consisting of a single neuron and all the muscle fibers it stimulates. JMyoglobin: Compound that stores oxygen in muscle cells. JMyosin: One of the two contractile proteins in muscle cells, the otherbeing actin. JNeurotransmitter: Chemical released from the ending of an axon that enables a nerve impulse to cross a synapse. JOrigin: Source; beginning; muscle attachment connected to a nonmoving part. JOxygen Debt: Amount of oxygen needed to reverse the effects produced in muscles functioning without oxygen. JPrime Mover: Muscle that performs a given movement; antagonist. JSpasm: A sudden, abnormal, involuntary muscular contraction, consisting of a continued muscular contraction or of a series of alternating muscular contractions and relaxations. JSynapse: Junction between two neurons or between a neuron and an effector. JSynergist: A substance or structure that enhances the work of another; a muscle that works with a prime mover to produce a given movement. JTendon: Cord of fibrous connective tissue that attaches a muscle to a bone. JTonus: Partially contracted state of muscle; also, tone.
2) Compare the 3 types of muscle tissue. Smooth Muscle: Makes up the walls of the hallow body organs as well as those of blood vessels and respiratory passageways and is under involuntary control. Produces peristalsis; contracts and relaxes slowly; may sustain contraction. Cardiac Muscle: Makes up the wall of the heart and creates the pulsing action of that organ and is under involuntary control. Pumps blood out of the heart; self-excitatory but influenced by nervous system and hormones. Skeletal Muscle: Striated muscle that is usually attached to the skeleton and is usually under voluntary control. Produces movement ion joints; stimulated by nervous system; contracts and relaxes rapidly.
3) Describe the 3 functions of skeletal muscle. a. Movement of the skeleton. Muscles are attached to bones and contract to change in position of the bones at a joint. b. Maintenance of posture. A steady partial contraction of muscle, known as muscle tone., keeps the body in position. Some of the muscles involved in maintaining posture are the large muscles of the thighs, back neck, and shoulders as well as the abdominal muscles. c. Generation of heat. Muscles generate most of the heat needed to keep the body at 37 degrees C. Heat is a natural byproduct of muscle cell metabolism. When we are cold, muscles can boost their heat output by the rapid small contractions we know of as shivering.
4) Briefly describe how skeletal muscle contract. Muscles are normally arranged in opposition so that as one group of muscles contract, another group 'relaxes' (in fact simply stretched) or lengthens. Antagonism in the transmission of nerve impulses (epsp and ipsp lateral balance) to the muscles means that it is impossible to stimulate the contraction of two antagonistic muscles at any one time. During ballistic motions such as throwing, the antagonist muscles act to 'brake' the agonist muscles throughout the contraction, particularly at the end of the motion. In the example of throwing, the chest and front of the shoulder (anterior Deltoid) contract to pull the arm forward, while the muscles in the back and rear of the shoulder (posterior Deltoid) also contract and undergo eccentric contraction to slow the motion down to avoid injury.
5) List the substance needed in muscle contraction and describe the function of each. Actin: A protein found especially in microfilaments (as those comprising myofibrils) and active in muscular contraction. Myosin: The commonest protein in muscle cells, a globulin responsible for the elastic and contractile properties of muscle and combining with actin to form actomyosin. ATP: Adenosine triphosphate; an adenosine-derived nucleotide that supplies large amounts of energy to cells for various biochemical processes, including muscle contraction Calcium: It enables the cross-bridges to form between actin and myosin so the sliding filament actin can begin.
6) Define the term oxygen debt. Oxygen debt is the amount of oxygen needed to reverse the effects produced in muscles functioning without oxygen.
7) Describe 3 compounds stored in muscle that are used to generate energy in highly active muscle cells. Myoglobin: Stores additional oxygen. This compound is similar to the bloods hemoglobin but is located specifically in muscle cells. Glycogen: Stores additional glucose. It is a polysaccharide made of multiple glucose molecules and it can be broken down into glucose when needed by the muscle cells. CreatinePhosphate: Stores energy. It is a compound similar to ATP, in that it has a high energy bond that releases energy hen it is broken. This energy is used to make ATP for muscle contraction when the muscle cell has used up its ATP.
8) Cite the effects of exercise on muscle. !@- Increase in the number of capillaries in the muscle tissue, which brings more blood to the cells. !@- Increase in the number of mitochondria to increase the production of ATP. !@- Increase in reserves of myoglobin, glycogen, and creatine phosphate to promote endurance.
9) Compare the working of muscles and bones to lever systems. Prime mover: A movement is preformed by a muscle. Antagonist: The muscle that produces an opposite movement to that of the prime mover. Synergists: “Helping” muscles, because they work with the prime movers to accomplish a movent. Three classes of levers: 1. Fulcrum (F) 2. Effort (E)/force 3. Resistance (R)/weight or load.

3) What are the classes of Micro organisms? Bacteria, Protozoa, Rickettsiae, Viruses, Antisepsis, Disinfection and Sterilization.
4) Explain and give examples of the following: a. Aseptic Technique: Prevents or inhibits growth of pathogenic organism but they are not effective against spores and viruses. An example of this is Alcohol. b. Disinfectant: Destroys or kills pathogenic organisms. It is not effective against spores and viruses. An example of these is bleach solution. c. Sterilization: Destroys all microorganisms, both pathogenic and nonpathogenic, including spores and viruses. An example of this is autoclave.
5) Describe Standard Precautions and when to use it. Standard Precautions are developed by the center for disease control and prevention. Every body fluid must be considered a potentially infectious material, and all patients must be considered potential source of infection. You deal with the standard precaution when you are dealing with blood or any other fluid that contains blood, urine, vomit and more.
6) Describe Transmission Based Isolation Precautions: a. Airborne Precautions: Used for patients known or suspected to be borne droplet nuclei, small particles of evaporated droplets that contains microorganism and remain suspended in the air or in dust particles. Examples of diseases that require this isolation are chicken pox’s, tuberculosis and more.
b. Droplet Precautions: Used when patients are known or suspected to be infected with pathogens transmitted by large-particle droplets expelled during coughing, sneezing, talking, or laughing. Examples of this precaution are Haemophilus, influenza, meningitis. c. Contact Precautions: Used when patients are known or suspected to be infected with epidemiologically. It spread rapidly from person to person. Examples of these precautions are any gastrointestinal respiratory, skin or wound infections.
7) Compare and contrast medical and surgical asepsis. Give examples. Medical Asepsis and surgical asepsis both are way to help stop the way disease to spread. They also want to help maintain cleanness. They both use cleaning hands to help to stop the spread of diseases, they also wear gloves. They both use equipments that are cleaned after every time after using them, the environment that they will work in will be cleaned. Surgical Asepsis uses other ways to help the spread of diseases they have to wear special gown; there equipment that they use is in a sterile package and there is a special way to open the package. Last they wear a mask, thing that they wear around there head and booties to prevent the spread of diseases. Medical Asepsis uses gloves, mask, gown to help the spread of diseases but they don’t have to wear the thing around there head. But both Asepsis are uses as a way to help not to spread the diseases.
8) Infections and disease may be acquired in varying ways. a. Differentiate between the following and give examples: i. Nosocomial Infections or disease: One acquired by an individual in a health care facility such as in a hospital and a long term care facility. Examples of these infections are staphylococcus, pseudomonas, and enterococci. ii. Opportunistic Infections or disease: Those that occur when the body is weak. These diseases do not usually occur in individuals with intact immune systems. Examples of these infections are the development of Kaposi’s sarcoma, pneumocystis carinii. iii. Endogenous Infections or disease: Infection or diseases within the body. Examples of these infections are metabolic disorder, congenital abnormalities, tumors, and infections caused by microorganisms within the body. iv. Exogenous Infections or disease: The infection or diseases outside the body. Examples of these infections are pathogenic organisms that invade the body, radiation, and chemical agents.
9) What is the single most effective way to bread the chain of infection and why? The single most effective way to bread the chain if infection is eliminating a part of the chain the infection or diseases will stop. This is because the chain will be broken up.
10) Demonstrate proper hand washing technique. Using soap to clean your hands, the water should be warm and when washing wash between your fingers clean your nails by putting your fingers against you palms, clean the top and back part of your hand, and clean your wrists. After you are done you should leave the water on and grab a towel dry your hands than take another towel don’t use the same towel and shut the water off. You should wash your hand for 15 to 20 seconds by ding that you can sing the happy birthday song 2 times.
11) Demonstrate proper wearing of PPE. When you are dealing with any infection or if you think it is infected. Also you wear them when you are dealing with any solid and liquid object that is part of the body.
12) Demonstrate applying sterile gloves. Picking up the first glove by grasping the glove on the top edge of the folded down cuff. Then you hold the glove securely by the cuff and slip the opposite hand into the glove. After you slip the glove under the cuff of the second glove, you lift from the package. Hold the gloved hand under the cuff while inserting the other land into the glove, insert the gloved fingers under the cuff, and pull out slightly, and turn the cuffs over and up without touching the inside of the gloves or skin. Last interfaces the fingers to position the gloves correctly, taking care not to touch the skin with the gloved hands.

3) Explain the causes and treatment for eating disorders and chemical abuse.
Eating disorders often develop from an excessive concern with appearance. Psychological or psychiatric help is usually needed to treat eating disorders.
Chemical abuse is the use of substances such as alcohol and drugs.This can occur in any life stage. Peer pressure, and anxiety can trigger this. Treatment is directed toward total rehabilitation that allows the chemical abuser to return to a productive and meaningful life.
4) Identify methods used to prevent suicide and list common warning signs.
Support, understanding, and psychological or psychiatric counseling are used to prevent suicide.
Warning signs: -sudden changes in appetite and sleep habits -withdrawal, depression, and moodiness -excessive fatigue or agitation -alcohol or drug abuse -injuring ones body -giving away possessions -saying goodbye to family and friends
5) Describe the 5 stages of grieving that occur in the dying patient and the role of the health care worker during each stage.
1. Denial is the “No, not me!” stage, which usually occurs when a person is first told of a terminal illness. The health care worker should listen to a patient and try to provide support without confirming or denying.
2. Anger occurs when the patient is no longer able to deny death. The health care worker should understand that this is anger and not a personal attack.
3. Bargaining occurs when patients accept death but want more time to live. The health care worker must again be supportive and be good listeners.
4. Depression occurs when patients realize that death will come soon and they will no longer be with their families or be able to complete their goals. The health care worker should provide a quiet understanding, support, and/or a simple touch.
5. Acceptance is the final stage. The health care worker must provide emotional support.
6) List 2 purposes of hospice care and justify the “right to die”.
Hospice care offers palliative care and provides care to the families who lost a loved one.
The right to die is another issue that health care workers must understand. Those who have a terminal illness, with no hope to be cured, should be allowed to refuse measures that would prolong life.

The Muscular System Ms. Collins PNWHBOCES
1) Define Key Terms on page 110.
JAcetylcholine: Neurotransmitter; released at synapses within the nervous system and at the
neuromuscular junction.
JActin: One of the two contractile proteins in muscle cells, the other being myosin.
JAntagonist: Muscle that has an action opposite that of a given movement; substance that opposes the
action of another substance.
JFascicle: Small bundle, as of muscle cells or nerve cell fibers.
JGlycogen: Compound built from glucose molecules that is stored for energy in liver and muscles.
JInsertion: Muscle attachment connected to a movable joint.
JLactic Acid: Organic acid that accumulates in muscle cells functioning without oxygen.
JMotor Unit: Group consisting of a single neuron and all the muscle fibers it stimulates.
JMyoglobin: Compound that stores oxygen in muscle cells.
JMyosin: One of the two contractile proteins in muscle cells, the other being actin.
JNeurotransmitter: Chemical released from the ending of an axon that enables a nerve impulse to
cross a synapse.
JOrigin: Source; beginning; muscle attachment connected to a nonmoving part.
JOxygen Debt: Amount of oxygen needed to reverse the effects produced in muscles functioning
without oxygen.
JPrime Mover: Muscle that performs a given movement; antagonist.
JSpasm: A sudden, abnormal, involuntary muscular contraction, consisting of a continued muscular
contraction or of a series of alternating muscular contractions and relaxations.
JSynapse: Junction between two neurons or between a neuron and an effector.
JSynergist: A substance or structure that enhances the work of another; a muscle that works with a
prime mover to produce a given movement.
JTendon: Cord of fibrous connective tissue that attaches a muscle to a bone.
JTonus: Partially contracted state of muscle; also, tone.
2) Compare the 3 types of muscle tissue.
Smooth Muscle: Makes up the walls of the hallow body organs as well as those of blood vessels and
respiratory passageways and is under involuntary control. Produces peristalsis; contracts
and relaxes slowly; may sustain contraction.
Cardiac Muscle: Makes up the wall of the heart and creates the pulsing action of that organ and is under
involuntary control. Pumps blood out of the heart; self-excitatory but influenced by
nervous system and hormones.
Skeletal Muscle: Striated muscle that is usually attached to the skeleton and is usually under voluntary
control. Produces movement ion joints; stimulated by nervous system; contracts and
relaxes rapidly.
3) Describe the 3 functions of skeletal muscle.
a. Movement of the skeleton. Muscles are attached to bones and contract to change in position of the
bones at a joint.
b. Maintenance of posture. A steady partial contraction of muscle, known as muscle tone., keeps the body
in position. Some of the muscles involved in maintaining posture are the large muscles of the thighs,
back neck, and shoulders as well as the abdominal muscles.
c. Generation of heat. Muscles generate most of the heat needed to keep the body at 37 degrees C. Heat is
a natural byproduct of muscle cell metabolism. When we are cold, muscles can boost their heat output
by the rapid small contractions we know of as shivering.
4) Briefly describe how skeletal muscle contract.
Muscles are normally arranged in opposition so that as one group of muscles contract, another group 'relaxes' (in fact simply stretched) or lengthens. Antagonism in the transmission of nerve impulses (epsp and ipsp lateral balance) to the muscles means that it is impossible to stimulate the contraction of two antagonistic muscles at any one time. During ballistic motions such as throwing, the antagonist muscles act to 'brake' the agonist muscles throughout the contraction, particularly at the end of the motion. In the example of throwing, the chest and front of the shoulder (anterior Deltoid) contract to pull the arm forward, while the muscles in the back and rear of the shoulder (posterior Deltoid) also contract and undergo eccentric contraction to slow the motion down to avoid injury.
5) List the substance needed in muscle contraction and describe the function of each.
Actin: A protein found especially in microfilaments (as those comprising myofibrils) and active in muscular
contraction.
Myosin: The commonest protein in muscle cells, a globulin responsible for the elastic and contractile
properties of muscle and combining with actin to form actomyosin.
ATP: Adenosine triphosphate; an adenosine-derived nucleotide that supplies large amounts of energy to
cells for various biochemical processes, including muscle contraction
Calcium: It enables the cross-bridges to form between actin and myosin so the sliding filament actin can
begin.
6) Define the term oxygen debt.
Oxygen debt is the amount of oxygen needed to reverse the effects produced in muscles functioning
without oxygen.
7) Describe 3 compounds stored in muscle that are used to generate energy in highly active muscle cells.
Myoglobin: Stores additional oxygen. This compound is similar to the bloods hemoglobin but is
located specifically in muscle cells.
Glycogen: Stores additional glucose. It is a polysaccharide made of multiple glucose molecules and it
can be broken down into glucose when needed by the muscle cells.
Creatine Phosphate: Stores energy. It is a compound similar to ATP, in that it has a high energy bond
that releases energy hen it is broken. This energy is used to make ATP for muscle
contraction when the muscle cell has used up its ATP.
8) Cite the effects of exercise on muscle.
!@- Increase in the number of capillaries in the muscle tissue, which brings more blood to the cells.
!@- Increase in the number of mitochondria to increase the production of ATP.
!@- Increase in reserves of myoglobin, glycogen, and creatine phosphate to promote endurance.
9) Compare the working of muscles and bones to lever systems.
Prime mover: A movement is preformed by a muscle.
Antagonist: The muscle that produces an opposite movement to that of the prime mover.
Synergists: “Helping” muscles, because they work with the prime movers to accomplish a movent.

Five parts of the Chain of Infection include:
1-causative agent
2-source or reservoir
3-portal of exit
4-portal of entry
5-susceptible
↓The chain eliminates mode of transmission spread of disease.
3) What are the classes of Micro organisms?
Bacteria, Protozoa, Rickettsiae, Viruses, Antisepsis, Disinfection and Sterilization.
4) Explain and give examples of the following:

An example of these is bleach solution.
c. Sterilization: Destroys all microorganisms, both pathogenic and nonpathogenic, including spores
and viruses.
An example of this is autoclave.
5) Describe Standard Precautions and when to use it.
Standard Precautions are developed by the center for disease control and prevention. Every body
fluid must be considered a potentially infectious material, and all patients must be considered
potential source of infection. You deal with the standard precaution when you are dealing with
blood or any other fluid that contains blood, urine, vomit and more.
6) Describe Transmission Based Isolation Precautions:
a. Airborne Precautions: Used for patients known or suspected to be borne droplet nuclei, small
particles of evaporated droplets that contains microorganism and remain
suspended in the air or in dust particles.
Examples of diseases that require this isolation are chicken pox’s,
tuberculosis and more.
b. Droplet Precautions: Used when patients are known or suspected to be infected with pathogens
transmitted by large-particle droplets expelled during coughing, sneezing,
talking, or laughing.
Examples of this precaution are Haemophilus, influenza, meningitis.
c. Contact Precautions: Used when patients are known or suspected to be infected with
epidemiologically. It spread rapidly from person to person.
Examples of these precautions are any gastrointestinal respiratory, skin or
wound infections.
7) Compare and contrast medical and surgical asepsis. Give examples.
Medical Asepsis and surgical asepsis both are way to help stop the way disease to spread. They
also want to help maintain cleanness. They both use cleaning hands to help to stop the spread
of diseases, they also wear gloves. They both use equipments that are cleaned after every time
after using them, the environment that they will work in will be cleaned. Surgical Asepsis uses
other ways to help the spread of diseases they have to wear special gown; there equipment that
they use is in a sterile package and there is a special way to open the package. Last they wear a
mask, thing that they wear around there head and booties to prevent the spread of diseases.
Medical Asepsis uses gloves, mask, gown to help the spread of diseases but they don’t have to
wear the thing around there head. But both Asepsis are uses as a way to help not to spread the
diseases.
8) Infections and disease may be acquired in varying ways.
a. Differentiate between the following and give examples:
i. Nosocomial Infections or disease: One acquired by an individual in a health care facility such
as in a hospital and a long term care facility.
Examples of these infections are staphylococcus,
pseudomonas, and enterococci.
ii. Opportunistic Infections or disease: Those that occur when the body is weak. These diseases
do not usually occur in individuals with intact immune
systems.
Examples of these infections are the
development of Kaposi’s sarcoma, pneumocystis
carinii.
iii. Endogenous Infections or disease: Infection or diseases within the body.
Examples of these infections are metabolic
disorder, congenital abnormalities, tumors, and
infections caused by microorganisms within the
body.
iv. Exogenous Infections or disease: The infection or diseases outside the body.
Examples of these infections are pathogenic
organisms that invade the body, radiation, and
chemical agents.
9) What is the single most effective way to bread the chain of infection and why?
The single most effective way to bread the chain if infection is eliminating a part of the chain
the infection or diseases will stop. This is because the chain will be broken up.
10) Demonstrate proper hand washing technique.
Using soap to clean your hands, the water should be warm and when washing wash between
your fingers clean your nails by putting your fingers against you palms, clean the top and back
part of your hand, and clean your wrists. After you are done you should leave the water on and
grab a towel dry your hands than take another towel don’t use the same towel and shut the
water off. You should wash your hand for 15 to 20 seconds by ding that you can sing the
happy birthday song 2 times.
11) Demonstrate proper wearing of PPE.
When you are dealing with any infection or if you think it is infected. Also you wear them
when you are dealing with any solid and liquid object that is part of the body.
12) Demonstrate applying sterile gloves.
Picking up the first glove by grasping the glove on the top edge of the folded down cuff. Then
you hold the glove securely by the cuff and slip the opposite hand into the glove. After you slip
the glove under the cuff of the second glove, you lift from the package. Hold the gloved hand
under the cuff while inserting the other land into the glove, insert the gloved fingers under the
cuff, and pull out slightly, and turn the cuffs over and up without touching the inside of the
gloves or skin. Last interfaces the fingers to position the gloves correctly, taking care not to
touch the skin with the gloved hands.
